Even with careful hiring, renovations sometimes go wrong. Work may be substandard, the project may stall, or a contractor may simply stop showing up. When that happens, your response in the first days matters enormously — the right steps preserve your leverage and your legal options, while the wrong ones can weaken your position. The goal is almost always to resolve the problem and get the work completed properly, and most disputes can be settled without lawyers if handled calmly and methodically. This guide lays out exactly what to do, in order, if a contractor does bad work in Ottawa.
Before you do anything else, build a clear record. Documentation is the foundation of every successful resolution.
Take detailed, dated photos and video of the deficient work. Gather your contract, the original quote, all receipts and proof of payment, and every text, email, and note from conversations. Write down a timeline of what was promised, what was delivered, and when. This record is what turns a he-said-...
For significant problems, consider having an independent contractor, home inspector, or engineer assess the work and document what is wrong and what it will cost to fix. A neutral professional opinion strengthens your position whether you are negotiating, escalating, or pursuing a claim.
Most problems are best solved by direct, firm communication while you still hold financial leverage.
Put your concerns in writing, referencing the specific terms of your contract and the deficiencies you have documented. Be factual and specific about what needs to be corrected and by when. Written communication creates a record and often prompts a cooperative contractor to make things right.
This is exactly why you keep a final holdback. Do not release the remaining payment until the deficiencies are corrected to the standard set out in your contract. The holdback is your strongest practical leverage to ensure the work is completed properly. Releasing it too early removes your best tool...
If direct communication does not resolve the issue, you have a series of escalating options.
Refer to the dispute resolution process in your contract, which ideally calls for mediation before litigation. You can also file a complaint with the Better Business Bureau and contact Consumer Protection Ontario, both of which create pressure and an official record. If the contractor belongs to an ...
For disputes up to $35,000, Ontario's Small Claims Court is accessible and does not require a lawyer, though legal advice helps. For larger amounts or complex cases, consult a construction lawyer. Your documentation, contract, and independent assessment are what make these avenues effective.
If a contractor disappears with your deposit and no work done, treat it as potential fraud — document everything, report it to police, and contact Consumer Protection Ontario. The smaller your deposit and the better your paper trail, the more recoverable your position.
Document everything immediately — dated photos and video of the deficiencies, your contract, the quote, receipts, and all communication. Then raise the issue in writing referencing your contract. Strong documentation is the foundation of every successful resolution.
Yes — this is why you keep a final holdback of 10% to 15%. Do not release the remaining payment until deficiencies are corrected to the standard in your contract. The holdback is your strongest practical leverage. Withholding amounts beyond the holdback should be done carefully and ideally with legal advice.
File a complaint with the Better Business Bureau and contact Consumer Protection Ontario, both of which create an official record. If the contractor belongs to an association like RenoMark, contact that body as well. For monetary claims, Small Claims Court handles disputes up to $35,000.
Treat it as potential fraud. Document the contract, payment, and all communication, report it to police, and contact Consumer Protection Ontario. A small deposit and a clear paper trail make recovery far more likely, which is why deposits should never exceed 10% to 15%.
For significant problems, yes. An independent contractor, home inspector, or engineer can document what is wrong and what it will cost to fix. A neutral professional assessment strengthens your position in negotiation, mediation, or court.
